Fixes PDA Chat Client not working properly after PDA loses charge (#19157)

fixes https://github.com/Aurorastation/Aurora.3/issues/19156

tl;dr: chat client is supposed to try turning the service back on
automatically when you open it, but it was only doing that if manually
disabled, which is a different state. this makes it do it if it's killed
(like via running out of charge) or disabled manually

- bugfix: "Fixed PDA Chat Client not working properly after a PDA loses
charge."
